ADJUSTABLE TABLE AND BOOK-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 248,894, dated November1, 1881.

Application filed November 17, 1880.

To all whom it may concern:

Be it known that I, CELESTIA D. S'rrr'r, of Titusville,in the county ofCrawford and State of Pennsylvania, have invented a new and usefulAdjustable Table and Book-Support, of which the following is aspecification.

The object of my invention is to provide a neat, convenient, andornamental book-support, easily adjusted as to height and position,which may be made a part of a library or drawing-room table, or beapplied to an invalid chairor bed. 1 attain thisin the mannershown inthe accompanying drawings, in which the book-support is shown as forminga part of a center-table Figure 1 being an elevation of the tableextended, and the book-support inclined on its axis, and Fig. 2 asimilar view, with the booksupport folded and the table closed. Figs. 3and 4 are enlarged views of the mechanism adapted for adjusting theheight of the table and book-rest.

The same letters are used in the several views to indicate the sameparts.

A A is the table top or leaves; B B, base; 0 0, adjustable standards, E,frame or booksupport, constructed as hereinafter described; F F, shaftsrevolving in journals or hearings in the standards 0 O, and with whichthe frame E revolves.

The frame E is constructed with a double hinge-joint in each side bar,which joints are covered by the sliding ferrules G G when the frame isopen, as shown in Fig. 1. There is also a drop-joint, H, in each shaft-F F.

I I are cords, upon which the book rests. K K are sliding bars, havingspring-fingers attached for holding the leaves of the book open.

When the table is open and the frame E extended theframe revolves withthe shaft F F, and may be secured in any position by a rack or clampupon the shaft.

When desired to close the table the frame E is brought toa horizontalposition,theferrules GGslipped to one side, uncovering the double jointin the side bars, when the frame folds downward, and the two sections ofthe table are brought together and secured by the springcatch L or anyother device, the frame E folding under the table and into recesses inthe standards 0 C.

For adjusting the height of the table I make the standards 0 G to slideup and down in the bases B B. The mechanism for holding them (No model.)

in any desired position is illustrated more fully in Figs. 3 and 4.

To the standard 0 is attached the spring M, engaging with the rack-teethN in the base B. This allows the standard 0 to be drawn upward, butprevents it from returning. To control this, 1 place between thestandard (J and the spring M the lever O, hinged to the standard andoperating against the spring. The leverO has an arm, flwhichis attachedto a rod, T, whieh,in turn, at its upper end is attached to an arm onthe shaft It, near the top of the standard 0-. This shaft has a milledhead, S. By turning the shaft R the lever O is raised, releasing thespring M from the rack-teeth N, and the standard 0 is allowed to movedownward with perfect freedom.

For application to an invalid-chair or bed I attach to either side ofthe chair or bed a socket similar to those in the bases B B,in which thestandards 0 G are adjusted, as above described. YVhen not in use thestandards O O are entirely withdrawn, and, with theframe E,folded andlaid away.

I claim as my invention 1. A folding book support or frame, E,constructed as describedfin combination with the adjustable standards 0and the jointed shafts F F on either side, the said shafts revolving inbearings in the adjustable standards (7 O, substantially as described.

2. In combination with an extension-table, the central folding frame,E,constructed as described, and the jointed shafts F F, said shaftsrevolving in hearings on the under side of the table-top A A,substantially as described, and for the purposes herein set forth.

3. For regulating the height of the table A, the combination of theadjustable standard 0, base B, provided with rack-teeth N, spring M,engaging with the teeth N, lever 0, rod T, and shaft R, substantially asdescribed.

4. The table-top A A, adjustable standards 0 0, central folding frame,E, constructed as described and revolving with the shafts F F, incombination with the base B B, each sec tion of the base being providedwith rackteeth N, spring M, engaging with the teeth N, lever 0, rod T,and shaft It, substantially as described,and for the purposes hereinsetforth.
